MANHATTAN, Kan. (AP) — Police in northeast Kansas are investigating possible charges after a man called for help, saying he feared for his safety after he was unable to pay a prostitute for sex.

The Topeka Capital-Journal reports (http://bit.ly/12iBURz ) the 23-year-old man summoned Riley County police to a mobile home in Manhattan around 2 a.m. Wednesday.

The man told officers he hired a Topeka woman online at an agreed rate of $400 for two hours of sex. When the two hours were up, the man said, he confessed to the woman that he had no money to pay her.

Police say the man called for help because he feared some kind of retaliation from the woman or her boss.
